Résumé

In this paper, a novel small-scale single-panel liquid-to-air membrane energy exchanger (LAMEE) test facility has been used to experimentally investigate the effect of different number of heat transfer units (NTU) and heat capacity ratio (Cr*) on the steady-state performance of the LAMEE. The small-scale single-panel LAMEE facilitates research and development of LAMEE prototypes and the evaluation of systems design parameters without manufacturing costs and time required to build full-scale prototypes. Lithium Chloride (LiCl) is used as a salt solution in the system, and the steady-state sensible, latent and total effectiveness of the LAMEE are evaluated for two different NTUs (4.5 and 5.8), and four different Cr* values (1, 3, 5 and 7) at summer AHRI conditions, which represents the air cooling and dehumidifying test case. Moreover, a numerical code is used to numerically model the small-scale single-panel LAMEE, and numerical results are compared with experimental data. The results show that the sensible, latent and total effectiveness of the LAMEE increase with both NTU and Cr*. Maximum experimental total effectiveness of 95% is achieved for the small-scale LAMEE at NTU=5.8 and Cr*=7. Also, the agreement between the experimental data and the numerical results is acceptable, and they are within the uncertainty range of the experimental data in most cases.
